I get this Caller ID somewhat often, although not as much as I used to. Called today, 03/30/2017, but the area code is in my call blocker so the phone doesn't ring, but the number still shows in the call log. I don't know anyone in that area code, anyway. They never leave a message on my answering machine so they aren't likely to be a valid and legal business, at least as they are supposed to be doing. BTW, that area code is in Southern California, and it belongs to Florence and L.A., excluding downtown L.A.
